Catches and Latches
Frequently Asked Questions
What are catches and latches?
Catches and latches are non-keyed hardware devices used to hold doors closed without locking them. Unlike deadbolts or keyed locks, they provide retention only. At National Lock Supply, we stock roller latches, ball catches, and magnetic catches for interior use.
How do they differ from keyed locks?
Locks provide security with keys or cylinders, while catches and latches only hold the door in place. They are often paired with push/pull hardware instead of knobs or levers.
What types exist?
Roller latches, ball catches, magnetic latches, and friction catches. Roller and ball types are adjustable for tension.
Where are they commonly used?
In closet doors, utility doors, cabinet doors, and interior non-locking applications, where security isn’t required but a door must stay closed.
What materials are used?
Brass, stainless steel, and nylon-tipped components for durability.
Are they ADA compliant?
Yes, when paired with push/pull plates or lever hardware that doesn’t require tight grasping.
Are catches and latches UL listed?
Most are not UL-rated, since they are not used in fire or security applications.
What finishes are available?
Polished Brass, Satin Chrome, Stainless Steel, and Oil-Rubbed Bronze.
Can they be adjusted?
Yes, roller and ball catches feature adjustable spring tension for proper holding strength.
